The sidewinder glides through harsh desert landscapes with astonishing fluidity and grace. Sure it's a snake, but a snake so flexible we designed our Sidewinder Shirt to give you that same kind of agility and ease. You'll move effortlessly all day thanks to 4-way flexible DuluthFlex® fabric, underarm gussets and a box pleat. And like its namesake, this shirt is built for searing climates: super-light, 3.2-oz. wicking performance fabric has UPF 30, wicks sweat, keeps you cool. Plus, there's even breathable mesh under the back cape. So pull on a Sidewinder and don't let summer heat or binding shirts get you rattled.
